Use Comm32 to quickly add Serial Communications capabilities to your applications.
Comm32 is compatible with MSComm in that it uses the same property names, methods and syntax which means that you can quickly add Comm32 to a VB6 project in place of MSComm32 without needing to change any of your code or learn any new syntax. (also works for other languages with minor syntax changes)

See Comm32 Installation for complete instructions - how to install Comm32 on your computer and how to add the Comm32 component to your projects.

The download contains a fully functional trial version of Comm32 as well as sample projects showing you how to use Comm32.

Context sensitive help means that while you're working in your project you can place the cursor on a property and press the F1 key on your keyboard to see the help page describing that property.

The help file also contains information about making RS232 cables and even shows how to make a loop back tester for testing your hardware and debugging your applications.

Fixes/Improvements

Error 8002 Invalid Port Number - When running your application in the IDE the com port is owned by the IDE - not by your application. If you end your application without closing the com port then the IDE would hold the com port open preventing the application from accessing the port again until you closed the IDE. This has now been resolved.
When using Microsoft's MSComm32 control you may be able to send data but when trying to receive you encounter a runtime error 8020. We've introduced a new Property ParallelEnable. When disabled it often avoids similar problems with our Comm32 control.

Latest version of the file Comm32.ocx is 3.2.0.82 released August 9. 2010 (The 'Version' property shows 3.2p)
